Objectives: 

To review and evaluate the validity of common perceptions and practices regarding radiation safety in orthopaedic trauma.

Design: 

Retrospective study.

Setting: 

Level 1 trauma center.

Subjects: 

N/A.

Intervention: 

The intervention involved personal protective equipment.

Main Outcome Measurements: 

The main outcome measurements included radiation dose estimates.

Results: 

Surgeon radiation exposure estimates performed at the level of the thyroid, chest, and pelvis demonstrate an estimated total annual exposure of 1521 mR, 2452 mR, and 1129 mR, respectively. In all cases, wearing lead provides a significant reduction (90% or better) in the amount of radiation exposure (in both radiation risk and levels of radiation reaching the body) received by the surgeon. Surgeons are inadequately protected from radiation exposure with noncircumferential lead. The commonly accepted notion that there is negligible exposure when standing greater than 6 feet from the radiation source is misleading, particularly when cumulative exposure is considered. Finally, we demonstrated that trauma surgeons specializing in pelvis and acetabular fracture care are at an increased risk of exposure to potentially dangerous levels of radiation, given the amount of radiation required for their caseload.

Conclusion: 

Common myths and misperceptions regarding radiation in orthopaedic trauma are unfounded. Proper use of circumferential personal protective equipment is critical in preventing excess radiation exposure.

骨科创伤外科医生的辐射暴露：解构普遍持有的神话和误解

目标： 

审查和评估关于骨科创伤中辐射安全的常见看法和实践的有效性。

设计： 

回顾性研究。

环境： 

一级创伤中心。

主题： 

不适用。

干涉： 

干预涉及个人防护设备。

主要成果测量： 

主要结果测量包括辐射剂量估计。

结果： 

在甲状腺、胸部和骨盆水平进行的外科医生辐射暴露估计显示，估计的年总暴露量分别为 1521 mR、2452 mR 和 1129 mR。在所有情况下，佩戴铅可以显着减少（90% 或更好）外科医生接受的辐射量（辐射风险和到达身体的辐射水平）。外科医生没有得到足够的保护，使其免受非周向铅的辐射照射。普遍接受的观点认为，当站在距离辐射源 6 英尺以上时，暴露量可以忽略不计，这是一种误导，尤其是在考虑累积暴露量时。最后，我们证明了专门从事骨盆和髋臼骨折护理的创伤外科医生暴露于潜在危险水平的辐射的风险增加，

结论： 

关于骨科创伤中辐射的常见神话和误解是没有根据的。正确使用周边个人防护设备对于防止过度辐射暴露至关重要。
